Check for leaks in the brake lines and around the brake calipers.
3
Examine brake pads for wear and thickness.
4
Inspect brake rotors for warping or scoring.

Solution

1. Preparation

Tools Required: Socket set, brake fluid, OBD-II scanner, multimeter, jack and jack stands.
Ensure vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect the brake pads for thickness; replace if below manufacturer's specifications (usually less than 3mm).
3. Remove the caliper bolts using a socket wrench and slide the caliper off.
4. Remove old brake pads and install new ones, ensuring they are correctly aligned.
5. Reinstall the caliper and torque bolts to manufacturer specifications (typically between 20-30 ft-lbs).

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are warped or excessively worn, remove them by unscrewing the caliper bracket.
2. Clean the hub surface where the rotor mounts.
3. Install new rotors, ensuring they are seated properly.
4. Torque rotor bolts to manufacturer specifications (usually around 80-100 ft-lbs).

4. Check Brake Fluid and System

Sub-steps:
1. Check brake fluid level in the master cylinder; refill with appropriate fluid (DOT 3 or DOT 4 as per manufacturer's specs).
2. Bleed the brake system to remove any air bubbles using a brake bleeder kit.
3. Ensure that all connections are tight and there are no leaks.

5. Test Brake Booster

Sub-steps:
1. With the engine off, press the brake pedal several times to deplete vacuum.
2. Start the engine; the brake pedal should drop slightly if the booster is functioning properly.
3. If there is no change, inspect the vacuum line for blockages or leaks and replace if necessary.
